wATER-oLosET VALVE.

SPECIFICATION forming Tf1 all whom t may concern,.-

` Be it known that I, JOHN DEMAR'EsT, of the city and State of New York, have invented an Improvement in Valves forfWater-Closets, of which the following is a specification.

In Letters Patent No. 260,953, granted-to me, there is a stand-pipe witha valve at the lower end of Aa tubular dani within said stand pipe.

VMy present invention relates to a valve that is specially adapted to water-closets provided with stand-pipes. In my improved valve a packing-gland is dispensed with; hence there is no risk of the stem being held by friction, and the action of the valve is more reliable.

vThe thin sheet or jet "of water that rushes through the hole around the valve-stem is received into a deiiecting-thimble, and conveyed by a tube -or hollow arm intothe standpipe. rIhe valve is below the seat and closes upwardly, so that in the normal position there is no leakage of water, and the small quantity of water that escapes around the valve-stemis only running while the water flows from the valve into the basin of the closet.

In the drawings, Figure l is a Vertical sec` tion of the valve and a portion of the standpipe, and Fig. 2 is a sectional plan lat the line @c x.

The stand-pipe e, cover o, cylindrical dam 7c', the valve-stem Z, pull m, and the pull-cup n are similar to those in my Patent No. 260,953, and do not require any further description. I remark that this stand-pipe maybe of any suitable character, and it is only introduced herein for the purpose of illustrating the manner in which my improved valve may be applied to the stand-pipe of closets of the general character represented in said patent.

The water-supply pipe u is coupled to one side of the valve-case b, and in thisV valve-case I) there is a valve, c, and valveseat c, and above the seat there is a hollow arm, e', with a coupling-screw at the end, by means of which a pipe is connected that passes to the basin of the Water-closet, so as to supply the flushingwater to the said closet. The septum v3 is above this arm e', and through it the stem k of the valve a passes, and above this septum t' holes farthest from part of Letters Patent No. 292,159, dated Januaryg22, 1884. ,'Appuc'nuon meri Armen 21, im. No modif,

there is a third hollow arm or tube, g, that is of a sufficient length to be screwed into a hole in the side of the standpipe e. This hollow' arm g is strong enough to support the valve case and the, valve-actuating lever, Vand it serves to convey into the stand-pipe any water that may pass through the hole in the septum and around the valve-stem k. Upon the upper end of the valve-stem there is a deflecting-thinible, m, that is hollowed out conically at its under side, so that any water that may spurt up through the opening for the valvestem will entr this thimble and be thrown down again into the tube y land run oft' to the stand-pipe. The exterior of the deilectingthimble is cylindrical, and it slides freely in the cylindrical upper portion ofthe valve-case at the end of the pipe g. In order to press upon this thimble and open the valve, I make use of the lever r, which has a fulcrum-pin, s, that passes through two lugs, q, upon the pipe g-one at each side of the lever. and lever there are two or more sets of holes for the fulcrum-pin s, so that said pin s may be changed in its position into either set of holes. When said pin is near the thimble, the movement of the thimble with a given length of motion at the long end of the lever will be less than it will when the'v pin s is in the set of the thimble. By this means the valve will be opened more or less, and,V as said valve closes automatically, and by the action of a variable chamber, the time' consumed in closing will vary, and a greater or less quantity of water will iow by the pipeI c to the-water-closet basin.

I have ,represented the nut or shoulder 3, upon the stem of the pull l, as the means for moving the lever i'. In this instance the valve In these lugs p is opened at the same time that the dam k is raised, so that the water will now to the closet basin.

Upon reference to Fig. 1 it will be seen that the valve-case is made in two parts, screwed together, the lower part forming the variable chamber, in which the cup-leather piston t slides. The valve-stem k is loose in the tubup lar stemt', that connects the valve a and cupleather piston. There 4are channels in or flattened sides to the valve-stem, so that water will pass freely up around the spindle when the spindle is pressed down in opening the valve; but there is a valve, fu, at the lower part of the spindle, that closcs.against the bottom end of the tubular` stein by the action of the spring o when pressure ou the upper end of the stem k is relieved, so that the variable chamber can only fill with water through the small hole 6 as the cup-leather piston and thc' valve rise gradually.

In order to prevent the small hole at 6 be coming obstructed with sediment which accumulates around the cup-leather piston, I make a tubular projection at one side of the stem l', and this rises above the cup-leather piston t, so that the small hole is above and out of the way of any sediment. Hence the valve is not liable to get out of order; but it will close with regularity, and the water will run the desired time into the closet-basin according to the extent of movement given to the valve in opening it.

The valve may be taken out for cleaning by simply unscrewing the bottom part of the valve-case without disturbing any of the parts that connect to the water-pipes.

I claim as my inventionl. rIhe valve-case and the valve having a stem passing through a septum in the case, a

tubular arm, y, above the septum, extending tothe closet,A and a dctlectingthimble upon the upper end of the valve-stein, substantially as set forth.

2. In a water-closet valve, the combination, with the valve-case, of the arm g, the lever above said arm for actuating the valve, flanges, and holes in the flanges and lever, and a movable pin by which the position of the fulcrum and the movement of the valve maybe varied, substantially as set forth.

3. In combination, with the stand-pipe in a Water-closet and the pull thereof, a valve and valve-case, a tubular arm between the standpipe and valve-case, and a lever pivoted upon the tubular arm and actuated by the pull, substantially as set forth.

4. ln a water-closet valve, a case having three branches, one for the inl et-water, another for the pipe leading to the closet-basin, and a third for leakage from the hole through which the valve stem passes, substantially as set forth.

Signed by me this 19th day of March, A. D. 1883.
